Product details
Overview
HER152G from Taiwan Semiconductor is a high-efficiency, glass-passivated single-die silicon rectifier diode rated for 100 V repetitive peak reverse voltage (VRRM), 1.5 A average forward current (IF), and 50 A non-repetitive surge current (IFSM). It features low forward voltage drop (1.0 V at 1.5 A, 25°C), fast reverse recovery time (50 ns), and operates up to 150°C junction temperature - deployed in DC-DC converters and switching-mode power supplies.
For engineers reviewing the HER152G datasheet, HER152G pinout, HER152G application, or HER152G equivalent, key selection considerations include its DO-204AC (DO-15) package, AEC-Q101 qualification option (HER152GH), 60°C/W junction-to-ambient thermal resistance, and verified performance under 8.3 ms half-sine surge conditions.
Technical Context
This device is a unidirectional, single-junction, planar passivated silicon rectifier optimized for high-frequency switching applications. Its 50 ns reverse recovery time and low 1.0 V forward voltage at rated current reduce conduction and switching losses in flyback and forward converter topologies.
The DO-204AC package provides mechanical robustness with pure tin-plated leads compliant to J-STD-002, UL 94V-0 molding compound, and JESD 201 Class 2 whisker resistance - supporting reflow and wave soldering in automotive and industrial production environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage before breakdown; defines usable input voltage range in AC/DC front-ends. |
| IF | 1.5 A - Continuous average forward current at 75°C ambient; sets steady-state power handling in 12–48 V output converters. |
| IFSM | 50 A - Peak non-repetitive surge current (8.3 ms half-sine); enables reliable operation during cold-start or line-transient events. |
| VF | 1.0 V @ 1.5 A, 25°C - Low conduction loss improves efficiency and reduces heatsink requirements in compact SMPS designs. |
| trr | 50 ns - Fast reverse recovery minimizes switching loss and EMI in >100 kHz switching applications. |
| RθJA | 60 °C/W - Thermal resistance determines required PCB copper area and airflow for thermal management at full load. |
| Junction Temp | −55°C to +150°C - Wide operating range supports under-hood automotive and industrial ambient conditions. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Dimensions per Taiwan Semiconductor Package Outline Drawing Rev. I2105.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1.0 A IF, 65 ns trr, TO-220AC package | Higher voltage rating but lower current; requires heatsink above 0.5 A continuous | Select when >400 V blocking is needed and board space permits larger package. |
| ON Semi MUR120 | 200 V VRRM, 1.0 A IF, 75 ns trr, DO-41 package | Lower current rating and slower recovery; smaller DO-41 footprint | Choose for cost-sensitive, lower-power (<10 W) designs where 100 V margin suffices. |
Compared with STTH1L06S and MUR120, HER152G delivers optimal balance of 100 V rating, 1.5 A current, 50 ns speed, and DO-15 manufacturability - making it preferred for mid-power 12–48 V output SMPS where thermal and layout constraints are tight.

FAQ
What is the maximum junction temperature rating for HER152G?
The HER152G has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Rev. I2105). This allows HER152G to operate reliably in under-hood automotive environments and enclosed industrial power supplies where ambient temperatures exceed 85°C. Derating curves confirm usable current down to 0.8 A at 125°C ambient.
Is HER152G RoHS and halogen-free compliant?
Yes, HER152G is fully RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" section of the Taiwan Semiconductor datasheet. The molding compound meets UL 94V-0 flammability standards, and the pure tin-plated leads satisfy J-STD-002 solderability requirements - ensuring compatibility with lead-free reflow processes and global environmental regulations.
What is the reverse recovery time (trr) of HER152G and how is it measured?
The HER152G has a typical reverse recovery time (trr) of 50 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This value applies to the entire HER151G–HER155G subgroup and reflects optimized minority-carrier lifetime control for reduced switching loss in high-frequency converters.
Does HER152G have AEC-Q101 qualification?
The base HER152G is not AEC-Q101 qualified, but the variant HER152GH is explicitly listed as AEC-Q101 qualified in the Ordering Information table of the Taiwan Semiconductor datasheet. HER152GH undergoes full stress testing per AEC-Q101 including HTOL, TCT, and ESD - making it suitable for automotive body electronics and powertrain auxiliary systems.
What is the thermal resistance (RθJA) of HER152G and how does it affect PCB layout?
HER152G has a junction-to-ambient thermal resistance (RθJA) of 60°C/W, measured on a standard JEDEC 2S2P test board. To maintain TJ ≤ 125°C at full 1.5 A load, the PCB must provide ≥ 1.5 cm² of 1 oz copper connected to both leads - underscoring the need for symmetric copper pour and minimal trace length in HER152G layout implementation.
